https://en.wikipedia.org/wiki/Dynamic%20frequency%20selection
|
Dynamic Frequency Selection (DFS) is a channel allocation scheme specified for wireless LAN, commonly known as Wi-Fi. It is designed to prevent electromagnetic interference by avoiding co-channel operation with systems that predated Wi-Fi, such as military radar, satellite communication, and weather radar, and also to provide on aggregate a near-uniform loading of the spectrum (uniform spreading). It was standardized in 2003 as part of IEEE 802.11h.
Radar Detection Mechanism
When starting operation, an access point automatically selects channels with low interference levels in a phase known as Channel Availability Check (CAC). During this phase, the access point is in a passive state scanning for radar signals. This commonly takes one to two minutes, but could take up to ten minutes. Thereafter, the access point performs In-Service Monitoring (ISM) to detect active radar signals; if radar is detected, and the access point is configured to automatically select a channel, it broadcasts a switch-channel event to its clients and follows by switching the channel. If channels were configured manually, the DFS mechanism causes the access point to go offline.
The actual mechanism, durations, radar pulse pattern, power levels, and frequency bands on which DFS is enforced vary by jurisdiction. DFS is mandated for the 5470–5725 MHz U-NII band in United States by the FCC. DFS is mandatory for the 5250–5350 and 5470–5725 MHz bands in India.

https://en.wikipedia.org/wiki/Microsatellite%20instability
|
Microsatellite instability (MSI) is the condition of genetic hypermutability (predisposition to mutation) that results from impaired DNA mismatch repair (MMR). The presence of MSI represents phenotypic evidence that MMR is not functioning normally.
MMR corrects errors that spontaneously occur during DNA replication, such as single base mismatches or short insertions and deletions. The proteins involved in MMR correct polymerase errors by forming a complex that binds to the mismatched section of DNA, excises the error, and inserts the correct sequence in its place. Cells with abnormally functioning MMR are unable to correct errors that occur during DNA replication and consequently accumulate errors. This causes the creation of novel microsatellite fragments. Polymerase chain reaction-based assays can reveal these novel microsatellites and provide evidence for the presence of MSI.
Microsatellites are repeated sequences of DNA. These sequences can be made of units of 1 to 6 base pairs in length that are repeated and reside adjacent to each other in the genome. Although the length of microsatellites can vary from person to person and contributes to the individual DNA "fingerprint", each individual has microsatellites of a set length. The most common microsatellite in humans is a dinucleotide repeat of the nucleotides C and A, which occurs tens of thousands of times across the genome. Microsatellites are also known as simple sequence repeats (SSRs).

https://en.wikipedia.org/wiki/Frederick%20Charles%20Frank
|
Sir Frederick Charles Frank, OBE, FRS (6 March 1911 – 5 April 1998) was a British theoretical physicist. He is best known for his work on crystal dislocations, including (with Thornton Read) the idea of the Frank–Read source of dislocations. He also proposed the cyclol reaction in the mid-1930s, and made many other contributions to solid-state physics, geophysics, and the theory of liquid crystals.
Early life and education
He was born in Durban, South Africa, although his parents returned to England soon afterwards. He was educated at Thetford Grammar School and Ipswich School and went on to study chemistry at Lincoln College, Oxford, gaining a doctorate at the university's Engineering Laboratory.
Career
Prior to World War II, he worked as a physicist in Berlin and as a colloid chemist in Cambridge. During World War II he joined the Chemical Defence Experimental Station at Porton Down, Wiltshire, but in 1940 was transferred to the Air Ministry's Assistant Directorate of Intelligence (Science) and spent the rest of the war with the Air Ministry. Due to his work he was made Officer of the Most Excellent Order of the British Empire in 1946.
After the war he moved to the University of Bristol Physics Department to do research in solid state physics, but switched to research on crystal dislocation. His work with William Keith Burton and Nicolás Cabrera was to demonstrate the role dislocations played in the growth of crystals.

https://en.wikipedia.org/wiki/Sequential%20quadratic%20programming
|
Sequential quadratic programming (SQP) is an iterative method for constrained nonlinear optimization which may be considered a quasi-Newton method. SQP methods are used on mathematical problems for which the objective function and the constraints are twice continuously differentiable.
SQP methods solve a sequence of optimization subproblems, each of which optimizes a quadratic model of the objective subject to a linearization of the constraints. If the problem is unconstrained, then the method reduces to Newton's method for finding a point where the gradient of the objective vanishes. If the problem has only equality constraints, then the method is equivalent to applying Newton's method to the first-order optimality conditions, or Karush–Kuhn–Tucker conditions, of the problem.
Algorithm basics
Consider a nonlinear programming problem of the form:
The Lagrangian for this problem is
where and are Lagrange multipliers.
The standard Newton's Method searches for the solution by iterating the following equation, where denotes the Hessian matrix:
.
However, because the matrix is generally singular (and therefore non-invertible), the Newton step cannot be calculated directly. Instead the basic sequential quadratic programming algorithm defines an appropriate search direction at an iterate , as a solution to the quadratic programming subproblem

https://en.wikipedia.org/wiki/Conio.h
|
{{DISPLAYTITLE:conio.h}}
conio.h is a C header file used mostly by MS-DOS compilers to provide console input/output. It is not part of the C standard library or ISO C, nor is it defined by POSIX.
This header declares several useful library functions for performing "istream input and output" from a program. Most C compilers that target DOS, Windows 3.x, Phar Lap, DOSX, OS/2, or Win32 have this header and supply the associated library functions in the default C library. Most C compilers that target UNIX and Linux do not have this header and do not supply the library functions. Some embedded systems or cc65 use a conio-compatible library.
The library functions declared by vary somewhat from compiler to compiler. As originally implemented in Lattice C, the various functions mapped directly to the first few DOS INT 21H functions. The library supplied with Borland's Turbo C did not use the DOS API but instead accessed video RAM directly for output and used BIOS interrupt calls. This library also has additional functions inspired from the successful Turbo Pascal one.
Compilers that target non-DOS operating systems, such as Linux or OS/2, provide similar solutions; the unix-related curses library is very common here. Another example is SyncTERM's ciolib. The version of done by DJ Delorie for the GO32 extender is particularly extensive.

https://en.wikipedia.org/wiki/Candidatus%20Carsonella%20ruddii
|
"Candidatus Carsonella ruddii" is an obligate endosymbiotic Gammaproteobacterium with one of the smallest genomes of any characterised bacteria.
This is the first, and as of February 2022 the only species described from the genus Candidatus Carsonella, named after Rachel Carson.
Endosymbiosis
The species is an endosymbiont that is present in all species of phloem sap-feeding insects known as psyllids. The endosymbionts occurs in a specialised structure known as the bacteriome.
C. ruddii is not completely parasitic in its relationship with its host insect; it supplies the host with some essential amino acids. It is therefore probably in the evolutionary process of becoming an organelle, similar to the mitochondria of eukaryotic cells that also evolved from an endosymbiont.
Genome
In 2006 the genome of Ca. C. ruddii strain Pv (Carsonella-Pv) of the hackberry petiole gall psyllid, Pachypsylla venusta, was sequenced at RIKEN in Japan and the University of Arizona. It was shown that the genome consists of a circular chromosome of 159,662 base pairs and that it has a high coding density (97%) with many overlapping genes and reduced gene length. The number of predicted genes was 182, also the lowest on record (NCBI-Genome). In comparison, Mycoplasma genitalium, which has the smallest genome of any free-living organism, has a genome of 521 genes. Numerous genes considered essential for life seem to be missing, suggesting that the species may have achieved organelle-like status.

https://en.wikipedia.org/wiki/Constraint%20%28mathematics%29
|
In mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. There are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. The set of candidate solutions that satisfy all constraints is called the feasible set.
Example
The following is a simple optimization problem:
subject to
and
where denotes the vector (x1, x2).
In this example, the first line defines the function to be minimized (called the objective function, loss function, or cost function). The second and third lines define two constraints, the first of which is an inequality constraint and the second of which is an equality constraint. These two constraints are hard constraints, meaning that it is required that they be satisfied; they define the feasible set of candidate solutions.
Without the constraints, the solution would be (0,0), where has the lowest value. But this solution does not satisfy the constraints. The solution of the constrained optimization problem stated above is , which is the point with the smallest value of that satisfies the two constraints.
Terminology
If an inequality constraint holds with equality at the optimal point, the constraint is said to be , as the point cannot be varied in the direction of the constraint even though doing so would improve the value of the objective function.
If an inequality constraint holds as a strict inequality at the optimal point (that is, does not hol

https://en.wikipedia.org/wiki/Bucladesine
|
Bucladesine is a cyclic nucleotide derivative which mimics the action of endogenous cAMP and is a phosphodiesterase inhibitor.
Bucladesine is a cell permeable cAMP analog. The compound is used in a wide variety of research applications because it mimics cAMP and can induce normal physiological responses when added to cells in experimental conditions. cAMP is only able to elicit minimal responses in these situations.
The neurite outgrowth instigated by bucladesine in cell cultures has been shown to be enhanced by nardosinone.
Bucladesine and seizure
The effect of bucladesine as a cAMP analog has been studied on the pentylenetetrazol-induced seizure in the wild-type mice. The data showed that bucladesine (300nM/mouse) reduced the seizure latency and threshold. In addition they found that combination of bucladesine and pentoxyfillin has additive effect on seizure latency and threshold.
Bucladesine and morphine withdrawal syndrome
Bucladesine (50-100nM/mouse) showed significant attenuation in the morphine withdrawal syndrome in the wild-type mice. In addition, its high dose (200nM/mouse) combination with H-89, as a protein kinase inhibitor, had additive attenuating effect on withdrawal syndromes.

Lanterna is a musical project led by guitarist Henry Frayne, formerly of Lodestone Destiny, The Syndicate, Ack-Ack, Area and The Moon Seven Times. Their tracks are evocative soundscapes, usually instrumental, that focus on Frayne's melodic guitar work awash in effects.
History
The first material released under the name Lanterna was a collaboration between Frayne, drummer Brendan Gamble and vocalist Lynn Canfield which the band self-released in 1992. Some of these tracks reappeared later that year on the Greek vinyl-only, Elfish label release Of Shapes That Haunt Thought's Wilderness. The recordings were re-released on both Parasol Records and Rykodisc in 1995 and 1998, respectively. The Rykodisc version led off with the song "Silent Hills." The track later appeared on the first disc of National Public Radio's "All Songs Considered" CD series, which collected songs used as interstitial music during All Things Considered. Five albums followed on Badman/Jemez Mountain.

The 1985 World Games were the second edition of the World Games, an international multi-sport event held in London. Three main venues were used, the main one being the Crystal Palace National Sports Centre. The opening ceremony was held at the Wembley Conference Centre. The master of ceremonies was television commentator Ron Pickering. Competitors were addressed by World Games Association President Dr Un Yong Kim, who told competitors, "the World Games is an innovation that deserves a warm welcome." Games Patron Ryoichi Sasakawa underwrote the financial shortfall to enable the Games to take place. British Olympic Association Chairman Charles Palmer opened the Games on behalf of the British sports community.
The song "World Game" by John Denver was adopted as the theme for the Games. Sports included field archery, taekwondo, karate, sambo, powerlifting, finswimming, roller sports, casting, korfball, water skiing, speedway, fistball, softball and netball.
The ground team at Crystal Palace was headed by former Nottingham Forest player Roy Dwight with assistance from Tosh Chamberlain. Television coverage was produced by Cheerleader productions. Commentators included Simon Reed, Martin Tyler, Gerald Sinstadt and Dave Lanning.
Titles
134 titles were awarded in 22 sports (not including two invitational sports).

https://en.wikipedia.org/wiki/Perceptual%20Audio%20Coder
|
Perceptual Audio Coder (PAC) is a lossy audio compression algorithm. It is used by Sirius Satellite Radio for their digital audio radio service.
Development
The original version of PAC developed by James Johnston and Anibal Ferreira at AT&T's Bell Labs has a flexible format and bitrate. It provides efficient compression of high-quality audio over a variety of formats from 16 kbit/s for a monophonic channel to 1024 kbit/s for a 5.1 format with four or six auxiliary audio channels, and provisions for an ancillary (fixed rate) and auxiliary (variable rate) side data channel. For stereo audio signals, it is claimed that it provides near-CD quality at about 56-64 kbit/s, with transparent coding at bit rates approaching 128 kbit/s.
Over the years PAC has evolved considerably. A known software implementation of this codec is CelestialTech's AudioLib. Later, it was considerably improved and renamed to ePAC (enhanced Perceptual Audio Coder) by Lucent, available in the AudioVeda music library manager.
iBiquity initially tested PAC for the HD-Radio IBOC digital radio upgrade for FM and AM, but chose an MPEG4-derived codec, HE-AAC, instead. MPEG-2 AAC is substantially similar to the original AT&T PAC algorithm written by Johnston and Ferreira, including the specifics of stereo pair coding, bitstream sectioning, handling of 1 or 2 channels at a time, multiple codebooks responding to the same largest absolute value, and block switching triggers.

https://en.wikipedia.org/wiki/Origin%20recognition%20complex
|
In molecular biology, origin recognition complex (ORC) is a multi-subunit DNA binding complex (6 subunits) that binds in all eukaryotes and archaea in an ATP-dependent manner to origins of replication. The subunits of this complex are encoded by the ORC1, ORC2, ORC3, ORC4, ORC5 and ORC6 genes. ORC is a central component for eukaryotic DNA replication, and remains bound to chromatin at replication origins throughout the cell cycle.
ORC directs DNA replication throughout the genome and is required for its initiation. ORC and Noc3p bound at replication origins serve as the foundation for assembly of the pre-replication complex (pre-RC), which includes Cdc6, Tah11 (a.k.a. Cdt1), and the Mcm2-Mcm7 complex. Pre-RC assembly during G1 is required for replication licensing of chromosomes prior to DNA synthesis during S phase. Cell cycle-regulated phosphorylation of Orc2, Orc6, Cdc6, and MCM by the cyclin-dependent protein kinase Cdc28 regulates initiation of DNA replication, including blocking reinitiation in G2/M phase.
The ORC is present throughout the cell cycle bound to replication origins, but is only active in late mitosis and early G1.
In yeast, ORC also plays a role in the establishment of silencing at the mating-type loci Hidden MAT Left (HML) and Hidden MAT Right (HMR). ORC participates in the assembly of transcriptionally silent chromatin at HML and HMR by recruiting the Sir1 silencing protein to the HML and HMR silencers.

Hinduism in Azerbaijan has been tied to cultural diffusion on the Silk Road. One of the remnants of once-dominant Hindu and Buddhist culture in the Caucasus is Surakhani, the site of the Ateshgah of Baku. As of 2020, there were about 500 Hindus in Azerbaijan.
History
In the Middle Ages, Hindu traders visited present-day Azerbaijan for Silk Road trade. The area was traversed by Hindu traders coming mostly from Multan and Sindh (in present-day Pakistan). The Atasghah in Surakhani was used by those traders to worship while in the area. Most of the traders left around the advent of the British Raj. The ceremonies were officiated by a Punjabi pandit. Historical sources indicate that locals worshipped at Surakhani even before the construction of the Atashgah, drawn by the "seven holes with burning flame" from which Surakhani takes its name. In the 1880s, the Czar Alexander III of Russia went to Azerbaijan to witness one of the last Hindu ceremonies performed there. After the 1890s, nearly all of the original Hindu merchants in Azerbaijan had died or left for The Indian Subcontinent.

Ultra High Frequency was a Long Island, New York based alternative rock band.
History
Formed in 2001 by Frank Fussa (vocals / guitar), Jonny Brown (guitar / vocals), Chris Johanidesz (bass / vocals) and Dennis Joseph (drums / vocals), the band would go on to produce two LPs, two EPs and a number of singles.
In 2005 the band signed with White Elephant Recordings and their next full length Matter in Time (2006) was recorded at Laundry Room Studios in Seattle, Washington by producer/engineer Barrett Jones, known for his prior work with Nirvana and Foo Fighters. Upon its release the band toured the US, including notable dates with fellow Long Island bands Brand New and As Tall As Lions and would play one of the last shows at famed NYC club CBGB.
In 2007 the band relocated to Los Angeles to write for a new record and shift their focus to touring on the West Coast. While in California the band released the single 44 Mph, a slowed down version of their 2006 single 88 Mph and recorded a set of demos. After a Halloween show at the Viper Room the band announced it was their last show and they were breaking up. Frank and Chris have emerged with a new band called Morning Fuzz.

The National Marrow Donor Program (NMDP) is a nonprofit organization founded in 1986 and based in Minneapolis, Minnesota, that operates the Be The Match Registry of volunteer hematopoietic cell donors and umbilical cord blood units in the United States.
The Be The Match Registry is the world's largest hematopoietic cell registry, listing more than 22 million individuals and more than 300,000 cord blood units. Hematopoietic cells from NMDP donors or cord blood units are used to transplant patients with a variety of blood, bone marrow or immune system disorders. As of December 2020, the NMDP had facilitated more than 100,000 transplants worldwide.
Activities
The NMDP coordinates the collection of hematopoietic ("blood-forming") cells that are used to perform what used to be called bone marrow transplants, but are now more properly called hematopoietic cell transplants. Patients needing a hematopoietic cell transplant but who lack a suitably matched donor in their family can search the Be The Match Registry for a matched unrelated donor or cord blood unit.
Hematopoietic cells are used to transplant patients with life-threatening disorders such as leukemia, lymphoma, aplastic anemia, as well as certain immune system and metabolic disorders. Hematopoietic cells can come from bone marrow, umbilical cord blood, or the circulating blood (peripheral blood stem cells (PBSCs)). Hematopoietic cells are a type of adult (i.e., non-embryonic) stem cell that can multiply and differentiat

https://en.wikipedia.org/wiki/Subgrain%20rotation%20recrystallization
|
In metallurgy, materials science and structural geology, subgrain rotation recrystallization is recognized as an important mechanism for dynamic recrystallisation. It involves the rotation of initially low-angle sub-grain boundaries until the mismatch between the crystal lattices across the boundary is sufficient for them to be regarded as grain boundaries. This mechanism has been recognized in many minerals (including quartz, calcite, olivine, pyroxenes, micas, feldspars, halite, garnets and zircons) and in metals (various magnesium, aluminium and nickel alloys).
Structure
In metals and minerals, grains are ordered structures in different crystal orientations. Subgrains are defined as grains that are oriented at a < 10–15 degree angle at the grain boundary, making it a low-angle grain boundary (LAGB). Due to the relationship between the energy versus the number of dislocations at the grain boundary, there is a driving force for fewer high-angle grain boundaries (HAGB) to form and grow instead of a higher number of LAGB. The energetics of the transformation depend on the interfacial energy at the boundaries, the lattice geometry (atomic and planar spacing, structure [i.e. FCC/BCC/HCP] of the material, and the degrees of freedom of the grains involved (misorientation, inclination). The recrystallized material has less total grain boundary area, which means that failure via brittle fracture along the grain boundary is less probable.

According to the official statistics, one gymnast, Adolf Spinnler, and one wrestler, Gustav Thiefenthaler, from Switzerland competed at the 1904 Summer Olympics in St. Louis, United States.
But there were more athletes with Swiss roots at the Olympics: Andreas Kempf competed in three gymnastics events, finishing 8th in the combined three events finals. He arrived in the United States in 1902 and represented the Kansas City Turnverein. Kempf applied for naturalization as a US citizen in 1908, but was denied citizenship. Emil Schwegler competed for the United States in three gymnastics events, representing the St. Louis Schweizer Turnverein. Born in Switzerland, he was naturalized as a US citizen with his parents and then was a college student in Kansas City, Missouri. And Oscar Schwab was born in Paris to a Swiss mother and was adopted by her American husband. He competed for the US in the quarter mile cycling race. After the games he raced mostly in Europe and was Swiss sprint champion in 1907.
In fact, eighteen-year old Gustav Tiefenthaler was also born in Switzerland, moved to the United States with his family when he was a child and was naturalized as a US citizen with his parents. So he was "less swiss" than Andreas Kempf. Tiefenthaler represented the South Broadway Athletic Club of St. Louis. At the Olympics, Tiefenthaler had a single bout in the men’s freestyle light flyweight event and lose, but still earned a bronze medal.

Interactive activation and competition (IAC) networks are artificial neural networks used to model memory and intuitive generalizations. They are made up of nodes or artificial neurons which are arrayed and activated in ways that emulate the behaviors of human memory.
The IAC model is used by the parallel distributed processing (PDP) Group and is associated with James L. McClelland and David E. Rumelhart; it is described in detail in their book Explorations in Parallel Distributed Processing: A Handbook of Models, Programs, and Exercises. This model does not contradict any currently known biological data or theories, and its performance is close enough to human performance as to warrant further investigation.

|
José de la Serna e Hinojosa, 1st Count of the Andes (May 1, 1770 – July 6, 1832) was a Spanish general and colonial official. He was the last Spanish viceroy of Peru to exercise effective power (January 29, 1821 to December 1824).
Background
He entered the army at a young age and saw his first service (as a cadet) in the defense of Ceuta against the Moors in 1784. Later he saw service against the French in Catalonia (1795), against the British under Admiral José de Mazarredo (1797), and in the second siege of Zaragoza (1809). During the latter battle he was captured and taken to France as a prisoner. He soon escaped.
Thereafter he traveled in Switzerland and the Orient, finally returning to Spain in 1811. In Spain he fought under Wellington in the Spanish War of Independence against the French, until the expulsion of the latter in 1813.
In command of Spanish forces in Alto Perú
In 1816, having risen to the rank of major general, he was appointed to take command of the Spanish forces in Peru battling the insurgents. He arrived in Callao on September 22, 1816 and proceeded directly to Alto Perú (now Bolivia). He took charge of the army in Cotagaita on November 12, 1816. Viceroy Joaquín de la Pezuela ordered De la Serna to attack Argentine insurgents in the province of Tucumán, but De la Serna opposed this plan, citing insufficient forces.
De la Serna had advanced as far as Salta when the Spanish were surprised by the appearance in February 1817 of José de San Martín's Arm

https://en.wikipedia.org/wiki/Protein%20turnover
|
In cell biology, protein turnover refers to the replacement of older proteins as they are broken down within the cell. Different types of proteins have very different turnover rates.
A balance between protein synthesis and protein degradation is required for good health and normal protein metabolism. More synthesis than breakdown indicates an anabolic state that builds lean tissues, more breakdown than synthesis indicates a catabolic state that burns lean tissues. According to D.S. Dunlop, protein turnover occurs in brain cells the same as any other eukaryotic cells, but that "knowledge of those aspects of control and regulation specific or peculiar to brain is an essential element for understanding brain function."
Protein turnover is believed to decrease with age in all senescent organisms including humans. This results in an increase in the amount of damaged protein within the body.
Protein turnover in the exercise science
Four weeks of aerobic exercise has been shown to increase skeletal muscle protein turnover in previously unfit individuals. A diet high in protein increases whole body turnover in endurance athletes.
Some bodybuilding supplements claim to reduce the protein breakdown by reducing or blocking the number of catabolic hormones within the body. This is believed to increase anabolism. However, if protein breakdown falls too low then the body would not be able to remove muscle cells that have been damaged during workouts which would in turn prevent the gro

https://en.wikipedia.org/wiki/Violarite
|
Violarite (Fe2+Ni23+S4) is a supergene sulfide mineral associated with the weathering and oxidation of primary pentlandite nickel sulfide ore minerals.
Violarite crystallises in the isometric system, with a hardness of 4.5 to 5.5 and a specific gravity of about 4, is dark violet grey to copper-red, often with verdigris and patina from associated copper and arsenic sulfides, and is typically in amorphous to massive infill of lower saprolite ultramafic lithologies.
Violarite has a characteristic violet colour, hence the name from the Latin 'violaris' alluding to its colour especially when viewed in polished section under a microscope.
Paragenesis
Violarite is formed by oxidisation of primary sulfide assemblages in nickel sulfide mineralisation. The process of formation involves oxidation of Ni2+ and Fe2+ which is contained within the primary pentlandite-pyrrhotite-pyrite assemblage.
Violarite is produced at the expense of both pentlandite and pyrrhotite, via the following basic reaction;
Pentlandite + Pyrrhotite --> Violarite + Acid
(Fe,Ni)9S8 + Fe(1-x)S + O2 → Fe2+Ni23+S4 + H2SO3
Violarite is also reported to be produced in low-temperature metamorphism of primary sulfides, though this is an unusual paragenetic indicator for the mineral.
Continued oxidation of violarite leads to replacement by goethite and formation of a gossanous boxwork, with nickel tending to remain as impurities within the goethite or haematite, or rarely as carbonate minerals.

Rebecca Luker (April 17, 1961 – December 23, 2020) was an American actress, singer, and recording artist, noted for her "crystal clear operatic soprano" and for maintaining long runs in Broadway musicals over the course of her three-decade-long career. The New York Times compared her to actresses such as Barbara Cook and Julie Andrews.
Beginning in regional theatre productions in the early 1980s, Luker made her Broadway debut in the original cast of The Phantom of the Opera as a Christine understudy and later took over the role as the principal actress. She would then originate the role of Lily in The Secret Garden on Broadway in 1991. She was nominated for three Tony Awards, for her performances as Magnolia in Show Boat (1994), Marian in The Music Man (2000) and Winifred in Mary Poppins (2006), another role that she created. She performed widely in theatre throughout her career and also gave concert and cabaret performances. She began acting in television in 2000 and made several films. Luker continued to act until the year of her death, at the age of 59, from amyotrophic lateral sclerosis. She can be heard on more than 20 cast albums and various other recordings.
Life and career
Luker, the daughter of Martha (Baggett), a high school treasurer, and Norse Doak Luker, Jr., a construction worker, was born in Birmingham, Alabama and grew up in the suburb of Helena. She attended the University of Montevallo, earning a BA in music, taking a year off in 1984 to perform in Sweene

Oregonite, Ni2FeAs2 is a nickel iron arsenide mineral first described from Josephine Creek, Oregon, United States.
Oregonite crystallises in the hexagonal crystal system and has a Mohs hardness of 5.
Occurrence
Oregonite is known, apart from its type locality, from the Chirnaisky Massif, Russia, associated with hydrothermal nickel minerals (millerite, heazelwoodite) in a metamorphosed ultramafic; from the Skouriatissa mine, Cyprus, associated with VMS mineralisation; and from the Kidd Mine, Timmins, Ontario, Canada within serpentinite-hosted chromite deposits.

Polydymite, Ni2+Ni23+S4, is a supergene thiospinel sulfide mineral associated with the weathering of primary pentlandite nickel sulfide.
Polydymite crystallises in the isometric system, with a hardness of 4.5 to 5.5 and a specific gravity of about 4, is dark violet gray to copper-red, often with verdigris and patina from associated copper and arsenic sulfides, and is typically in amorphous to massive infill of lower saprolite ultramafic lithologies.
Polydymite is the nickel equivalent of violarite and in many cases these two minerals are formed together, potentially in solid solution.
Common contaminants of polydymite are cobalt and iron. Polydymite forms a series with linnaeite, Co+2Co+32S4.
Paragenesis
Polydymite is formed by oxidisation of primary sulfide assemblages in nickel sulfide mineralisation. The process of formation involves oxidation of Ni2+ and Fe2+ which is contained within the primary pentlandite-pyrrhotite-pyrite assemblage.
Continued oxidation of polydymite leads to replacement by goethite and formation of a gossanous boxwork, with nickel tending to remain as impurities within the goethite or hematite, or rarely as carbonate minerals.
Occurrence
Polydymite is reported widely from the oxidised regolith above primary nickel sulfide ore systems worldwide. It is less common than related violarite, due to the high iron content of most primary sulfides.
Economic importance
Polydymite is an important transitional ore in many nickel sulfide mines, as it

https://en.wikipedia.org/wiki/Modified%20starch
|
Modified starch, also called starch derivatives, are prepared by physically, enzymatically, or chemically treating native starch to change its properties. Modified starches are used in practically all starch applications, such as in food products as a thickening agent, stabilizer or emulsifier; in pharmaceuticals as a disintegrant; or as binder in coated paper. They are also used in many other applications.
Starches are modified to enhance their performance in different applications. Starches may be modified to increase their stability against excessive heat, acid, shear, time, cooling, or freezing; to change their texture; to decrease or increase their viscosity; to lengthen or shorten gelatinization time; or to increase their visco-stability.
Modification methods
Acid-treated starch (INS 1401), also called thin boiling starch, is prepared by treating starch or starch granules with inorganic acids, e.g. hydrochloric acid breaking down the starch molecule and thus reducing the viscosity.
Other treatments producing modified starch (with different INS and E-numbers) are:
dextrin (INS 1400), roasted starch with hydrochloric acid
alkaline-modified starch (INS 1402) with sodium hydroxide or potassium hydroxide
bleached starch (INS 1403) with hydrogen peroxide
oxidized starch (INS 1404, E1404) with sodium hypochlorite, breaking down viscosity
enzyme-treated starch (INS 1405), maltodextrin, cyclodextrin

https://en.wikipedia.org/wiki/Pipe%20network%20analysis
|
In fluid dynamics, pipe network analysis is the analysis of the fluid flow through a hydraulics network, containing several or many interconnected branches. The aim is to determine the flow rates and pressure drops in the individual sections of the network. This is a common problem in hydraulic design.
Description
To direct water to many users, municipal water supplies often route it through a water supply network. A major part of this network will consist of interconnected pipes. This network creates a special class of problems in hydraulic design, with solution methods typically referred to as pipe network analysis. Water utilities generally make use of specialized software to automatically solve these problems. However, many such problems can also be addressed with simpler methods, like a spreadsheet equipped with a solver, or a modern graphing calculator.
Deterministic network analysis
Once the friction factors of the pipes are obtained (or calculated from pipe friction laws such as the Darcy-Weisbach equation), we can consider how to calculate the flow rates and head losses on the network. Generally the head losses (potential differences) at each node are neglected, and a solution is sought for the steady-state flows on the network, taking into account the pipe specifications (lengths and diameters), pipe friction properties and known flow rates or head losses.
The steady-state flows on the network must satisfy two conditions:

"DNA" is the second episode of the science fiction sitcom Red Dwarf Series IV and the twentieth episode in the series' run. It was first broadcast on the British television channel BBC2 on 21 February 1991, although it was planned to be broadcast as the fifth episode, it was moved forward in the schedule by the BBC. Written by Rob Grant and Doug Naylor, and directed by Ed Bye, the episode revolves around the genetic engineering technology that the crew discover.
Plot
Red Dwarf encounters a drifting spacecraft which Arnold Rimmer, Dave Lister, Kryten, and Cat decide to investigate. Once on board, the group split into pairs. While Rimmer and Kryten find the remains of a mutated human with three heads, Cat accidentally activates a machine that turns Lister into a chicken. When the others arrive, Kryten determines that the ship's crew were researching DNA modifications and that the machine Cat used can rewrite the DNA of anything with organic matter. When an attempt to reverse the effect on Lister changes him into a hamster, Cat repeats the actions he did to change him. However, while Lister is restored to his human body, Kryten finds himself turned into a human, due to his brain being part-organic.
Returning to Red Dwarf, Kryten is initially ecstatic at being human, but finds he cannot conduct certain functions that he did as a mechanoid, and soon regrets the change after he insults his mechanoid spare heads, as well as revealing his sexual arousal to machines in a machine cat

|
Acinic cell carcinoma is a malignant tumor representing 2% of all salivary tumors. 90% of the time found in the parotid gland, 10% intraorally on buccal mucosa or palate. The disease presents as a slow growing mass, associated with pain or tenderness in 50% of the cases. Often appears pseudoencapsulated.
Diagnosis
Basophilic, bland cells similar to acinar cells. Growth pattern: solid - acinar cells, microcytic - small cystic spaces mucinous or eosinophilic, papillary-cystic - large cystic lined by epithelium, follicular - similar to thyroid tissue.
These tumors, which resemble serous acinar cells, vary in their behavior from locally aggressive to blatantly malignant.
It can also appear in the breast. The pancreatic form of acinic cell carcinoma is a rare subtype of exocrine pancreatic cancer. Exocrine pancreatic cancers are the most common form of pancreatic cancer when compared to endocrine pancreatic cancer.
Acinic cell carcinomas arise most frequently in the parotid gland. Other sites of primary tumors have included the submandibular gland and other major and minor salivary glands. There have been rare cases of primary tumors involving the parapharyngeal space and the sublingual gland.
Prognosis
Prognosis is good for acinic cell carcinoma of the parotid gland, with five-year survival rates approaching 90%, and 20-year survival exceeding 50%. Patients with acinic cell carcinomas with high grade transformation (sometimes also called dedifferentiation) have significant

https://en.wikipedia.org/wiki/Giant-cell%20fibroma
|
Giant-cell fibroma is a type of fibroma not associated with trauma or irritation. It can occur at any age and on a mucous membrane surface. The most common oral locations are on the gingiva of the mandible, tongue, and palate. It is a localized reactive proliferation of fibrous connective tissue.
Giant-cell fibroma (GCF) is a benign non-neoplastic lesion first described by Weathers and Callihan (1974). It occurs in the first three decades of life and predominates in females (Houston, 1982; Bakos, 1992). Clinically, the GCF presents as an asymptomatic, papillary and pedunculated lesion. The most predominant location is the mandibular gingiva (Houston, 1982; Bakos, 1992). Histologically, the GCF is distinctive, consisting of fibrous connective tissue without inflammation and covered with stratified squamous hyperplastic epithelium. The most characteristic histological feature is the presence of large spindle-shaped and stellate-shaped mononuclear cells and multinucleated cells. These cells occur in a variety of lesions, such as the fibrous papule of the nose, ungual fibroma, acral fibrokeratoma, acral angiofibroma and desmoplastic fibroblastoma (Swan, 1988; Pitt et al., 1993; Karabela-Bouropoulou et al., 1999; Jang et al., 1999).
Despite many studies, the nature of the stellated multinucleate and mononuclear cell is not clear (Weathers and Campbell, 1974; Regezi et al., 1987; Odell et al., 1994; Magnusson and Rasmusson, 1995).

Granular cell tumor is a tumor that can develop on any skin or mucosal surface, but occurs on the tongue 40% of the time.
It is also known as Abrikossoff's tumor, granular cell myoblastoma, granular cell nerve sheath tumor, and granular cell schwannoma. Granular cell tumors (GCTs) affect females more often than males.
Pathology
Granular cell tumors are derived from neural tissue, as can be demonstrated by immunohistochemistry and ultrastructural evidence using electron microscopy. These lesions characteristically consist of polygonal cells with bland nuclei, abundant cytoplasm and fine eosinophilic cytoplasmic granules. The tumor cells stain positively for S-100 as they are of Schwann cell origin. Both malignant and benign versions of the tumor exist, where malignant tumors are characterized histologically by features such as spindling, high nuclear to cytoplasmic ratios, pleomorphism, and necrosis.
Multiple granular cell tumors may seen in the context of LEOPARD syndrome, due to a mutation in the PTPN11 gene.
These tumors, on occasion, may appear similar to neoplasms of renal (relating to the kidneys) origin or other soft tissue neoplasms.
Treatment
The primary method for treatment is surgical, not medical. Radiation and chemotherapy are not needed for benign lesions and are not effective for malignant lesions.
Benign granular cell tumors have a recurrence rate of 2% to 8% when resection margins are deemed clear of tumor infiltration. When the resection margins of a

Hans Friedrich Gadow (8 March 1855 – 16 May 1928) was a German-born ornithologist who worked in Britain. His work on the classification of birds based on anatomical and morphological characters was influential and made use of by Alexander Wetmore in his classification of North American birds.
Gadow was born in Stary Kraków (Pomerania), the son of an inspector of the Prussian royal forests. He studied at the universities of Berlin, Jena and Heidelberg. At Jena he studied under Ernst Haeckel and at Heidelberg University under the anatomist Karl Gegenbaur. After graduation he travelled to the Natural History Museum in London in 1880 at the request of Albert Günther, to work on the museum's Catalogue of Birds. Gadow also established the first new sequence of bird orders and families that departed from earlier works in being based on phylogenetic principles based on a comparison of anatomical and morphological features and made use of the studies made by Max Fürbringer. This sequence was continued with modification by Alexander Wetmore and James L. Peters and followed from the 1930s to the 1960s. Gadow prepared Volume VIII on the titmice, shrikes and nuthatches, and Volume IX on the sunbirds and honeyeaters.
In 1884 Gadow succeeded Osbert Salvin as Curator of the Strickland Collection at Cambridge University, as well as being appointed Lecturer on the Morphology of Vertebrates. He became a member of the British Ornithologists' Union in 1881 and a fellow of the Royal Society in

https://en.wikipedia.org/wiki/Central%20giant-cell%20granuloma
|
Central giant-cell granuloma (CGCG) is a localised benign condition of the jaws. It is twice as common in females and is more likely to occur before age 30. Central giant-cell granulomas are more common in the anterior mandible, often crossing the midline and causing painless swellings.
Signs and symptoms
CGCG is the most common giant cell lesion of the jaws. These lesions are localised fibrous tissue tumours which contain osteoclasts and are usually several centimetres across. Frequently, a painless swelling that grows and expands rapidly is present. This growth can also erode through bone including the alveolar ridge, resulting in a soft tissue swelling that is purple in colour. Paresthesia of the lip has also been observed. Resorption of tooth roots is seen in 37% of cases compared to displacement of teeth in 50%. Two-thirds of lesions are found anterior to molars in the mandible, where teeth have deciduous predecessors.
CGCGs are twice as likely to affect females and usually seen in those under 30-years. However, can be seen in a broad age range.
Noonan syndrome
Multiple CGCGs can be found in individuals with Noonan syndrome. Mutations in PTPN11 or RAS pathway genes are seen.
Diagnosis
Radiographically, CGCGs have a rounded cyst-like radiolucent area with a well-defined margin with 53% showing scalloped margins. They can have a multilocular (honeycomb or soap bubble) appearance.

forms superficially in the gingiva overlying the involved erupting tooth as soft, rounded and bluish swelling.
Histopathological features
The epithelial lining of eruption cyst is similar to that of the dentigerous cyst (non-keratinized stratified squamous epithelium), so the eruption cyst is considered a superficial dentigerous cyst.
The fibrous capsule shows inflammatory cells possibly as a result of trauma.
The epithelial lining of the cyst is separated from the alveolar mucosa by a thin layer of fibrous tissue with the epithelial tags of cystic epithelium facing those of the alveolar mucosa.
The cystic cavity may contain blood in addition to the yellowish protein fluid as a result of trauma.
Management
The cyst roof may be drained with its fluid to allow the tooth to erupt although most of them burst spontaneously.

https://en.wikipedia.org/wiki/White%20sponge%20nevus
|
White sponge nevus (WSN) is an autosomal dominant condition of the oral mucosa (the mucous membrane lining of the mouth). It is caused by a mutations in certain genes coding for keratin, which causes a defect in the normal process of keratinization of the mucosa. This results in lesions which are thick, white and velvety on the inside of the cheeks within the mouth. Usually, these lesions are present from birth or develop during childhood. The condition is entirely harmless, and no treatment is required.
Signs and symptoms
It presents itself in the mouth, most frequently as a thick, bilateral, symmetrical white plaques with a spongy, corrugated or velvety texture. Most usually, the lesions are on the buccal mucosa, but sometimes on the labial mucosa, alveolar ridge, floor of the mouth, ventral surface of the tongue or soft palate. The gingival margin and dorsum of the tongue are almost never affected. Less commonly, sites outside the mouth are affected, including the nasal, esophageal, laryngeal, anal and genital mucosae. It usually is present from birth, or develops during childhood. Rarely, the lesions may develop during adolescence. Apart from the appearance of the affected areas, there are usually no other signs or symptoms.
Pathophysiology
WSN is caused by a mutation of the keratin 4 or keratin 13 genes, located respectively at human chromosomes 12q13 and 17q21-q22. The condition is inherited in an autosomal dominant manner. This indicates that the defective gene resp

https://en.wikipedia.org/wiki/Logic%20optimization
|
Logic optimization is a process of finding an equivalent representation of the specified logic circuit under one or more specified constraints. This process is a part of a logic synthesis applied in digital electronics and integrated circuit design.
Generally, the circuit is constrained to a minimum chip area meeting a predefined response delay. The goal of logic optimization of a given circuit is to obtain the smallest logic circuit that evaluates to the same values as the original one. Usually, the smaller circuit with the same function is cheaper, takes less space, consumes less power, has shorter latency, and minimizes risks of unexpected cross-talk, hazard of delayed signal processing, and other issues present at the nano-scale level of metallic structures on an integrated circuit.
In terms of Boolean algebra, the optimization of a complex boolean expression is a process of finding a simpler one, which would upon evaluation ultimately produce the same results as the original one.
Motivation
The problem with having a complicated circuit (i.e. one with many elements, such as logic gates) is that each element takes up physical space and costs time and money to produce. Circuit minimization may be one form of logic optimization used to reduce the area of complex logic in integrated circuits.
With the advent of logic synthesis, one of the biggest challenges faced by the electronic design automation (EDA) industry was to find the most simple circuit representation of the g

https://en.wikipedia.org/wiki/Weighted%20fair%20queueing
|
Weighted fair queueing (WFQ) is a network scheduling algorithm. WFQ is both a packet-based implementation of the generalized processor sharing (GPS) policy, and a natural extension of fair queuing (FQ). Whereas FQ shares the link's capacity in equal subparts, WFQ allows schedulers to specify, for each flow, which fraction of the capacity will be given.
Weighted fair queuing is also known as packet-by-packet GPS (PGPS or P-GPS) since it approximates generalized processor sharing "to within one packet transmission time, regardless of the arrival patterns."
Parametrization and fairness
Like other GPS-like scheduling algorithms, the choice of the weights is left to the network administrator. There is no unique definition of what is "fair" (see for further discussion).
By regulating the WFQ weights dynamically, WFQ can be utilized for controlling the quality of service, for example, to achieve guaranteed data rate.
Proportionally fair behavior can be achieved by setting the weights to , where is the cost per data bit of data flow . For example, in CDMA spread spectrum cellular networks, the cost may be the required energy (the interference level), and in dynamic channel allocation systems, the cost may be the number of nearby base station sites that can not use the same frequency channel, in view to avoid co-channel interference.
Algorithm
In WFQ, a scheduler handling flows is configured with one weight for each flow. Then, the flow of number will achieve an average

https://en.wikipedia.org/wiki/Alveolar%20soft%20part%20sarcoma
|
Alveolar soft part sarcoma, abbreviated ASPS, is a very rare type of soft-tissue sarcoma, that grows slowly and whose cell of origin is unknown.
ASPS arises mainly in children and young adults and can migrate (metastasize) into other parts of the body, typically the lungs and the brain. Typically, ASPS arises in muscles and deep soft tissue of the thigh or the leg (lower extremities), but can also appear in the upper extremities (hands, neck, and head). While ASPS is a soft tissue sarcoma, it can also spread and grow inside the bones.
Etymology
The term alveolar comes from the microscopic pattern, visible during the analysis of slides of ASPS under the microscope in histopathology. The tumor cells seem to be arranged in the same pattern as the cells of the small air sacks (alveoli) in the lungs. However, this is just a structural similarity. ASPS was first described and characterized in 1952.
ASPS is a sarcoma, and that indicates that this cancer initially arises from tissue of embryonic mesenchymal origin. (The fertilized egg divides and redivides forming a sphere. Early in embryogenesis, dimples appear in the poles of the sphere and burrow through the sphere forming an inner passage that will ultimately form the gut. Malignancies arising from cells that were originally part of the outer layer of the sphere and those that were part of the embryonic tunnel are termed carcinomas; malignancies arising from the cells between the outer layer and the inner burrow are terme

https://en.wikipedia.org/wiki/Auxiliary%20cell
|
The auxiliary cell is a spore-like structure that form within the fungal family Gigasporaceae (order Gigasporales). Auxiliary cells have thin cell walls, (spiny), papillate, knobby or sometimes smooth surfaces, and are formed from hyphae after spore germination before the formation of mycorrhizae, and then on the extraradical hyphae in the soil. They may not be 'cells' in the biological sense of the word, as they are structures found with coenocytic hyphae belonging to members of the phylum (division) Glomeromycota. Mostly they are known from members of the Gigasporaceae. Currently this family contains Gigaspora, Scutellospora and Racocetra, but there are other generic names that have not been widely accepted (Dentiscutata, Cetraspora, Fuscutata and Quatunica) — all of these form auxiliary cells. Members of the genus Pacispora (another genus in the Diversisporales) are also said to produce a kind of auxiliary cell but this requires further confirmation.

|
According to van der Waals, the theorem of corresponding states (or principle/law of corresponding states) indicates that all fluids, when compared at the same reduced temperature and reduced pressure, have approximately the same compressibility factor and all deviate from ideal gas behavior to about the same degree.
Material constants that vary for each type of material are eliminated, in a recast reduced form of a constitutive equation. The reduced variables are defined in terms of critical variables.
The principle originated with the work of Johannes Diderik van der Waals in about 1873 when he used the critical temperature and critical pressure to derive a universal property of all fluids that follow the van der Waals equation of state. It predicts a value of that is found to be an overestimate when compared to real gases.
Edward A. Guggenheim used the phrase "Principle of Corresponding States" in an opt-cited paper to describe the phenomenon where different systems have very similar behaviors when near a critical point.
There are many examples of non-ideal gas models which satisfy this theorem, such as the van der Waals model, the Dieterici model, and so on, that can be found on the page on real gases.

Douglas Echols was convicted in a 1986 rape case. In 2002, his charges were finally cleared through DNA testing after he served over five years in prison. In 2005, a resolution was introduced in the Georgia Assembly by Representatives Tom Bordeaux and Chuck Sims requesting $1.6 million as compensation for his incarceration; however, the resolution was not approved.
The charges
On February 1, 1986, a young woman, Donna Givens, was leaving a Savannah nightclub in the early hours of the morning. As she left, three men accosted her, forced her into a car and drove her into an unknown neighborhood. Two of the men brought her into a house and raped her. Later, while they were arguing, Givens managed to escape and called the police. When asked to show police the location of her rape, Givens brought police to the house of Samuel Scott, where he and Echols were inside. She identified Echols as the man who held her down during the rape (this identification may have been based on suggestive ID procedures by the police including photo displays). Scott fled the scene because he had cocaine on him. Echols gave a false name. Even though Echols and Scott claimed mistaken identity and had two people testify to their whereabouts at the time of the incident, the court convicted them both based on Givens’ eyewitness identification and identification of the house. In the trial, Echols refused to testify against Scott. On March 26, 1987, Scott received a life sentence plus 20 years. Echols receiv

https://en.wikipedia.org/wiki/Multi-label%20classification
|
In machine learning, multi-label classification or multi-output classification is a variant of the classification problem where multiple nonexclusive labels may be assigned to each instance. Multi-label classification is a generalization of multiclass classification, which is the single-label problem of categorizing instances into precisely one of several (greater than or equal to two) classes. In the multi-label problem the labels are nonexclusive and there is no constraint on how many of the classes the instance can be assigned to.
Formally, multi-label classification is the problem of finding a model that maps inputs x to binary vectors y; that is, it assigns a value of 0 or 1 for each element (label) in y.
Problem transformation methods
Several problem transformation methods exist for multi-label classification, and can be roughly broken down into:
Transformation into binary classification problems
The baseline approach, called the binary relevance method, amounts to independently training one binary classifier for each label. Given an unseen sample, the combined model then predicts all labels for this sample for which the respective classifiers predict a positive result. Although this method of dividing the task into multiple binary tasks may resemble superficially the one-vs.-all (OvA) and one-vs.-rest (OvR) methods for multiclass classification, it is essentially different from both, because a single classifier under binary relevance deals with a single label, witho

|
A parabolic partial differential equation is a type of partial differential equation (PDE). Parabolic PDEs are used to describe a wide variety of time-dependent phenomena, including heat conduction, particle diffusion, and pricing of derivative investment instruments.
Definition
To define the simplest kind of parabolic PDE, consider a real-valued function of two independent real variables, and . A second-order, linear, constant-coefficient PDE for takes the form
and this PDE is classified as being parabolic if the coefficients satisfy the condition
Usually represents one-dimensional position and represents time,
and the PDE is solved subject to prescribed initial and boundary conditions.
The name "parabolic" is used because the assumption on the coefficients is the same as the condition
for the analytic geometry equation
to define a planar parabola.
The basic example of a parabolic PDE is the one-dimensional heat equation,
where is the temperature at time and at position along a thin rod, and is a positive constant (the thermal diffusivity). The symbol signifies the partial derivative of with respect to the time variable , and similarly is the second partial derivative with respect to . For this example, plays the role of in the general second-order linear PDE:
, , and the other coefficients are zero.
The heat equation says, roughly, that temperature at a given time and point rises or falls at a rate proportional to the difference between the temperatur

(English: Resonance) is the directorial debut by Bengali filmmaker Aniruddha Roy Chowdhury. The film premiered at the 2006 International Film Festival of India.
(meaning "resonance" in Bengali) explores the relationships of two married couples, and the impacts and consequences of their relationships.
Synopsis
Rahul, a creative and sensitive individual, arrives at a lonely hill station in Sikkim to help build a new holiday resort. The friendship between the two couples, Rahul and Nandita and Amit and Preeti, paves the way for a deeper bond between Rahul and Preeti. Towards the end of the movie, this "anuranan" between the two is misunderstood by society, including Amit. This misunderstanding intensifies when Rahul suddenly dies, leaving Nandita lonely. The fact that the love between Rahul and Nandita was pure does not prevent Nandita from falling prey to the rumors as well. All the four main characters are depicted as lost and lonely.

https://en.wikipedia.org/wiki/Penalty%20method
|
Penalty methods are a certain class of algorithms for solving constrained optimization problems.
A penalty method replaces a constrained optimization problem by a series of unconstrained problems whose solutions ideally converge to the solution of the original constrained problem. The unconstrained problems are formed by adding a term, called a penalty function, to the objective function that consists of a penalty parameter multiplied by a measure of violation of the constraints. The measure of violation is nonzero when the constraints are violated and is zero in the region where constraints are not violated.
Example
Let us say we are solving the following constrained problem:
subject to
This problem can be solved as a series of unconstrained minimization problems
where
In the above equations, is the exterior penalty function while are the penalty coefficients. In each iteration k of the method, we increase the penalty coefficient (e.g. by a factor of 10), solve the unconstrained problem and use the solution as the initial guess for the next iteration. Solutions of the successive unconstrained problems will asymptotically converge to the solution of the original constrained problem.
Practical application
Image compression optimization algorithms can make use of penalty functions for selecting how best to compress zones of colour to single representative values.

Robotix is an annual robotics and programming event that is organised by the Technology Robotix Society at the Indian Institute of Technology Kharagpur (IIT Kharagpur). It is held during Kshitij, the institute's annual techno-management festival. Participation is open to college students. The event gives contestants an opportunity to showcase their talents in the fields of mechanical robotics, autonomous robotics and programming.
History
Robotix started in 2001 as an in-house event for the students of IIT Kharagpur. Kunal Sinha, Saurabh Prasad and Varun Rai created the event for IDEON, the school's techno-management festival. The inaugural event hosted eight teams. In 2003, the IDEON festival was reorganized and renamed to Kshitij. Robotix is now organized under Kshitij.
Event participation has increased over the years: Robotix 2006 had 220 teams, Robotix 2007 had 546 teams, and Robotix 2008 had over 1000 teams.
Robotix celebrated its tenth edition in 2010 with an array of challenging problem statements. Robotix 2011 conducted a water surface event, R.A.F.T., in which over 250 teams participated.
Events
Events during Robotix are conducted under three categories: manual, autonomous and programming/online. In the manual events, the participant handles the robot by using a remote control. The remote system may be wired or unwired. The robot then has to perform the specified task, which is usually something mechanical. In the autonomous events, the robots act independently; p

In mathematical finance, the SABR model is a stochastic volatility model, which attempts to capture the volatility smile in derivatives markets. The name stands for "stochastic alpha, beta, rho", referring to the parameters of the model. The SABR model is widely used by practitioners in the financial industry, especially in the interest rate derivative markets. It was developed by Patrick S. Hagan, Deep Kumar, Andrew Lesniewski, and Diana Woodward.
Dynamics
The SABR model describes a single forward , such as a LIBOR forward rate, a forward swap rate, or a forward stock price. This is one of the standards in market used by market participants to quote volatilities. The volatility of the forward is described by a parameter . SABR is a dynamic model in which both and are represented by stochastic state variables whose time evolution is given by the following system of stochastic differential equations:

|
The Liberator was a monthly socialist magazine established by Max Eastman and his sister Crystal Eastman in 1918 to continue the work of The Masses, which was shut down by the wartime mailing regulations of the U.S. government. Intensely political, the magazine included copious quantities of art, poetry, and fiction along with political reporting and commentary. The publication was an organ of the Communist Party of America (CPA) from late 1922 and was merged with two other publications to form The Workers Monthly in 1924.
History
The Liberator focused on international news, featuring war correspondent and Communist Labor Party founder John Reed reporting on the ongoing situation in Soviet Russia; reports were filed from across post-war Europe by Robert Minor, Frederick Kuh, and Crystal Eastman.
As with The Masses, The Liberator relied heavily upon political art, including contributions from Maurice Becker, E.E. Cummings, John Dos Passos, Fred Ellis, Lydia Gibson, William Gropper, Ernest Hemingway, Helen Keller, J.J. Lankes, Boardman Robinson, Edmund Wilson, Wanda Gág, and Art Young. Each color cardstock cover of The Liberator was unique. Poetry and fiction fleshed out its pages, including work by Carl Sandburg, Claude McKay, Arturo Giovannitti, and others.
Maintaining a low price for the elaborate publication came at a huge cost, however. To economize, ultra-thin newsprint was used for the magazine's pages — cheap and high in acid content. The result was a fragile and e

https://en.wikipedia.org/wiki/P-rep
|
In statistical hypothesis testing, p-rep or prep has been proposed as a statistical alternative to the classic p-value. Whereas a p-value is the probability of obtaining a result under the null hypothesis, p-rep purports to compute the probability of replicating an effect. The derivation of p-rep contained significant mathematical errors.
For a while, the Association for Psychological Science recommended that articles submitted to Psychological Science and their other journals report p-rep rather than the classic p-value, but this is no longer the case.
Calculation
Approximation from p
The value of the p-rep (prep) can be approximated based on the p-value (p) as follows:
The above applies for one-tailed distributions.
Criticism
The fact that the p-rep has a one-to-one correspondence with the p-value makes it clear that this new measure brings no additional information beyond that conveyed by the significance of the result. Killeen acknowledges this lack of information, but suggests that p-rep better captures the way naive experimenters conceptualize p-values and statistical hypothesis testing.
Among the criticisms of p-rep is the fact that while it attempts to estimate replicability, it ignores results from other studies which can accurately guide this estimate. For example, an experiment on some unlikely paranormal phenomenon may yield a p-rep of 0.75. Most people would still not conclude the probability of a replication was 75%. Rather, they would conclude it i

PECOTA, an acronym for Player Empirical Comparison and Optimization Test Algorithm, is a sabermetric system for forecasting Major League Baseball player performance. The word is a backronym based on the name of journeyman major league player Bill Pecota, who, with a lifetime batting average of .249, is perhaps representative of the typical PECOTA entry. PECOTA was developed by Nate Silver in 2002–2003 and introduced to the public in the book Baseball Prospectus 2003. Baseball Prospectus (BP) has owned PECOTA since 2003; Silver managed PECOTA from 2003 to 2009. Beginning in Spring 2009, BP assumed responsibility for producing the annual forecasts, making 2010 the first baseball season for which Silver played no role in producing PECOTA projections.
One of several widely publicized statistical systems of forecasts of player performance, PECOTA player forecasts are marketed by BP as a fantasy baseball product. Since 2003, annual PECOTA forecasts have been published both in the Baseball Prospectus annual books and, in more detailed form, on the BaseballProspectus.com subscription-based website. PECOTA also inspired some analogous projection systems for other professional sports: KUBIAK for the National Football League, SCHOENE and CARMELO for the National Basketball Association, and VUKOTA for the National Hockey League.
PECOTA forecasts a player's performance in all of the major categories used in typical fantasy baseball games; it also forecasts production in advanced saberm

https://en.wikipedia.org/wiki/Hit%20to%20lead
|
Hit to lead (H2L) also known as lead generation is a stage in early drug discovery where small molecule hits from a high throughput screen (HTS) are evaluated and undergo limited optimization to identify promising lead compounds. These lead compounds undergo more extensive optimization in a subsequent step of drug discovery called lead optimization (LO). The drug discovery process generally follows the following path that includes a hit to lead stage:
Target validation (TV) → Assay development → High-throughput screening (HTS) → Hit to lead (H2L) → Lead optimization (LO) → Preclinical development → Clinical development
The hit to lead stage starts with confirmation and evaluation of the initial screening hits and is followed by synthesis of analogs (hit expansion). Typically the initial screening hits display binding affinities for their biological target in the micromolar (10−6 molar concentration) range. Through limited H2L optimization, the affinities of the hits are often improved by several orders of magnitude to the nanomolar (10−9 M) range. The hits also undergo limited optimization to improve metabolic half life so that the compounds can be tested in animal models of disease and also to improve selectivity against other biological targets binding that may result in undesirable side effects.
On average, only one in every 5,000 compounds that enters drug discovery to the stage of preclinical development becomes an approved drug.

https://en.wikipedia.org/wiki/Lecithin%20cholesterol%20acyltransferase%20deficiency
|
Lecithin cholesterol acyltransferase deficiency is a disorder of lipoprotein metabolism. The disease has two forms: Familial LCAT deficiency, in which there is complete LCAT deficiency, and Fish-eye disease, in which there is a partial deficiency.
Lecithin cholesterol acyltransferase catalyzes the formation of cholesterol esters in lipoproteins.
Signs and symptoms
Symptoms of the familial form include visual impairment caused by diffuse corneal opacities, target cell hemolytic anemia, and kidney failure. Less common symptoms include atherosclerosis, hepatomegaly (enlarged liver), splenomegaly (enlarged spleen), and enlarged lymph nodes.
Fish-eye disease is less severe and most commonly presents with impaired vision due to corneal opacification. It rarely presents with other findings, although, atherosclerosis, hepatomegaly, splenomegaly, and lymphadenopathy can occur. Carlson and Philipson found that the disease was named so because the cornea of the eye was so opaque or cloudy with dots of cholesterol that it resembled a boiled fish.
If an individual only carries one copy of the mutated gene, they typically do not show symptoms.
Pathophysiology
A deficiency of LCAT causes accumulation of unesterified cholesterol in certain body tissues. Cholesterol effluxes from cells as free cholesterol and is transported in HDL as esterified cholesterol. LCAT is the enzyme that esterifies the free cholesterol on HDL to cholesterol ester and allows the maturation of HDL. LCAT deficien

Livewire, is a segmentation technique which allows a user to select regions of interest to be extracted quickly and accurately, using simple mouse clicks. It is based on the lowest cost path algorithm, by Edsger W. Dijkstra. Firstly convolve the image with a Sobel filter to extract edges. Each pixel of the resulting image is a vertex of the graph and has edges going to the 4 pixels around it, as up, down, left, right. The edge costs are defined based on a cost function. In 1995, Eric N. Mortensen and William A. Barrett made some extension work on livewire segmentation tool, which is known as Intelligent Scissors.
Livewire segmentation
The user sets the starting point clicking on an image's pixel, known as an anchor. Then, as he starts to move the mouse over other points, the smallest cost path is drawn from the anchor to the pixel where the mouse is over, changing itself if the user moves the mouse. If he wants to choose the path that is being displayed, he simply clicks the image again.
One can easily see in the right image, that the places where the user clicked to outline the desired region of interest are marked with a small square. It is also easy to see that the livewire has snapped on the image's borders.

The Census in Pakistan (), is a decennial census and a descriptive count of Pakistan's population on Census Day, and of their dwellings, conducted and supervised by the Pakistan Bureau of Statistics. The 2017 Census in Pakistan marks the first census to take place in Pakistan since 1998. The most recent census was the 2023 Pakistani census.
Overview
A national census is mandated by the Constitution of Pakistan to be held every ten years. After the independence of Pakistan in 1947, the first census took place in 1951 under Finance Minister Sir Malik Ghulam, serving under Prime Minister Liaquat Ali Khan. Since 1951, there have been only 6 nationwide censuses (1961, 1972, 1981, 1998 and 2017). Delays and postponements have often been due to politicization. Pakistan's last completed census took place in 2017. The next national census was scheduled to take place in 2001 and later 2008, and again in 2010, but none of those plans could materialize. There were multiple census counts completed for the latest round in April 2012, but were subsequently thrown out as being "unreliable". A UN led census was to be conducted with staff training and GPS digitisation. As of 2015, the population of Pakistan is estimated at 191.71 million. As of 2016, the population of religious minorities in Pakistan have increased to 3 million. On 25 August 2017, the official results declared Pakistan's population to be 207.74 million.

Almaški Kraj () is an urban neighborhood of the city of Novi Sad, Serbia. It is situated between the Almaška church and the Saborna church and includes parts of the Podbara, Salajka and Stari Grad neighborhoods. There is a cemetery nearby by the same name -- Almaški cemetery.
History and culture
It was settled in 1718 by Serb families from the village Almaš, who thus named this part of the city Almaški Kraj ("the Almaš quarter"). The Almaš Orthodox church was built here in 1797. It is the largest Orthodox church in Novi Sad. The oldest cultural-scientific institution of Serbia, Matica srpska, is also located in Almaški Kraj.

Radio Trinidad was the oldest radio station in Trinidad and Tobago. It began broadcasting in 1947 at 11B Maraval Road in Port of Spain on the frequency 730 AM.
Over the years, the station successfully hosted a wide variety of programmes including soap operas, local and international news, educational documentaries such as the School Broadcasting Unit's show, which aired around 10a.m. on Mondays to Fridays when school was in session, and The Passing Parade hosted by John Doremus.
The station's announcers included June Gonsalves, Barbara Assoon, Glen Antoine, Sam Ghany, Val Douglas, Russell Winston, Trevor McDonald, Errol Chevalier, David Evelyn, Patrick Mathura, Peter Minshall, Don Proudfoot, Bob Gittens and Ashton Chambers.
Two of the most popular programmes were:
Sunday Serenade, a show that featured performers of the day including the Mighty Sparrow and Ken Hutcheon), broadcast at 11.00 a.m. on Sundays and hosted by Sam Ghany.
Auntie Kay, a children's talent show named after its presenter Kathleen Davis, which ran on Sundays at 2 p.m. and was sponsored by the Bermudez Biscuit Company. The back-up band was Choy Aming and the featured pianists were Aldwyn Albino and Dawlett Ahee.
Among other regular features were the Cook Caribbean Jazz programme (which took its name from a Trinidad recording company, Cook Caribbean, that originally produced 78rpm records and later continued with the 33 format), and The Indian Hour at 6 p.m. every day. There was also a programme for chi

|
The splendid lanternshark (Etmopterus splendidus) is a shark of the family Etmopteridae found in the western Pacific at depths between 120 and 210 m. Through the classification of Etmopterus species into several clades based on the positioning of their bioluminescent photophores, the splendid lanternshark can be considered a member of the Etmopterus pusillus clade.
Its length is up to 30 cm.
Reproduction is ovoviviparous.
Physiological Features and Adaptations
Bioluminescence
Patterning
The patterns of bioluminescent photophores found on the rostrum, dorsal area, and around the spine of splendid lantern sharks are similar to those of other members of the family Etmopteridae, namely Etmopterus spinax and Etmopterus molleri, but there are important differences. Dorsal photophores in all three species are arranged in three lines running the length of the back, but what distinguishes the splendid lanternshark from the other species is the longitudinal line of the dorsal area. This line is different from other species' in that it is significantly thicker. The bioluminescence spectra wavelength of Etmopterus splendidus is 476 nm, which is the wavelength light is present in the depths they are normally found. This is significant as it allows their bioluminescence to hide the sharks from predators and prey.
The photophores of Etmopterus splendidus are typical of etmopterid sharks, “i.e. a cluster of photocytes enclosed in a pigmented sheath and surmounted by pigmented and le

Indicazione geografica tipica () is the third of four classifications of wine recognized by the government of Italy. Created to recognize the unusually high quality of the class of wines known as Super Tuscans, IGT wines are labeled with the locality of their creation. However, they do not meet the requirements of the stricter DOC or DOCG designations, which are generally intended to protect traditional wine formulations such as Chianti or Barolo. It is considered broadly equivalent to the former French vin de pays classification (which is now generally protected as Protected geographical indication (French: Indication Géographique Protégée) under EU law. Wines from the Aosta Valley, where the French language is co-official, may state Vin de pays on the label in place of Indicazione geografica tipica. This classification is seen to be a higher quality wine than vino da tavola.

https://en.wikipedia.org/wiki/Turbinaria%20ornata
|
Turbinaria ornata is a tropical brown algae of the order Fucales native to coral reef ecosystems of the South Pacific. Turbinaria ornata is more commonly referred to as crowded sea bells in the US and crowned sea bells worldwide. It can quickly colonize these ecosystems due in part to its method of dispersing by detaching older and more buoyant fronds that travel on surface currents, sometimes in large rafts of many individual thalli, or fronds. Some scientists are investigating whether the increase in density of seaweeds, and a decrease in living coral density, on coral reef ecosystems indicates a change in the health of the reef, focusing studies on this particular species of brown alga.
Description
Yellow in color but can also be dark brown. It can span anywhere from 2-20 CM tall. A good way to describe it would be a club made up of spikey flowers. Turbinaria ornata can alter its morphology and strength of macroalgae in response to hydrodynamic forces.
Distribution and habitat
Widely distributed in the central and western Pacific and Indian oceans. Turbinaria ornata flourishes in tropical areas such as the Hawaiian islands and Tahiti. Very common in rocky interditdal areas. Most of the time they are the most abundant species of algae in the areas where they are found, with massive colonies. Although It is considered an invasive species in some places, Turbinaria Ornata is not considered a problem species in the Hawaiian islands. Turbinaria ornata have had a massiv

https://en.wikipedia.org/wiki/Mediastinal%20germ%20cell%20tumor
|
Mediastinal germ cell tumors are tumors that derive from germ cell rest remnants in the mediastinum. Germ cell tumors most commonly occur in the gonad but occasionally elsewhere.
Signs and symptoms
Unlike benign germ cell tumors of the mediastinum, malignant mediastinal tumors are usually symptomatic at the time of diagnosis. Most mediastinal malignant tumors are large and cause symptoms by compressing or invading adjacent structures, including the lungs, pleura, pericardium, and chest wall.
Seminomas grow relatively slowly and can become very large before causing symptoms. Tumors 20 to 30 cm in diameter can exist with minimal symptomatology.
Rare cases of adult onset acute megakaryoblastic leukemia are associated with malignant mediastinal germ cell tumor. In these cases, the mediastinal germ cell tumor develops before or concomitantly with but not after acute megakaryoblastic leukemia. The three most common genetic aberrations in the bone marrow cells of these individuals (representing ~65% of all cases) are inversions in the long arm of chromosome 12, trisomy 8, and an extra X chromosome. In several of these cases, the genetic aberrations in the malignant megakaryoblasts were similar to those in the malignant mediastinal germ cells. These results and those of other analyses suggest that the two malignancies derive from a common founding clone of cells (i.e. a set of genetically identical cells).
Cause
Some investigators suggest that this distribution arises as a conseq

Gera Midirna Keya Gebriel ("Gera Midir and Keya Gebriel") was one of the 105 woredas in the Amhara Region of Ethiopia. It is partly named after the northern district of the former province of Menz, Gera Meder. Located at the eastern edge of the Ethiopian highlands in the Semien Shewa Zone, Gera Midira Keya Gebriel was bordered on the south by Mam Midrina Lalo Midir, on the southwest by the Jamma River which separated it from Moretna Jiru, on the northwest by the Qechene River which separates it from the Debub Wollo Zone, on the north by Gishe, and on the east by the Oromia Zone. The administrative center of this woreda was Mehal Meda; other towns include Zemero. It was divided for Menz Gera Midir and Menz Keya Gebreal woredas.
Elevations in Gera Midirna Keya Gebriel range between 1000 and 4000 meters above sea level. The highest point in this woreda, as well as the Zone, is Mount Abuye Meda (4012 meters) near the eastern border.
Demographics
Based on figures published by the Central Statistical Agency in 2005, this woreda has an estimated total population of 183,027, of whom 92,599 are men and 90,428 are women; 14,014 or 7.66% of its population are urban dwellers, which is less than the Zone average of 11.8%.

Berehet (Amharic: በረኸት) is one of the woredas in the Amhara Region of Ethiopia. Part of the Semien Shewa Zone, Berehet is bordered on the south by the Germama River which separates it from Menjarna Shenkora, on the west by Hagere Mariamna Kesem, on the north by Asagirt, and on the east by the Afar Region. The major town in Berehet is Metiteh Bila.
Berehet is the location of the Battle of Bereket, fought 19 November 1855. In this battle, the last Shewan nobles to resist Emperor Tewodros II were defeated by his general Ras Ingida, and seeing that further defiance was futile they surrendered the young heir to the Shewan throne, Menelik.
Also during 1933 there was a battle between patriots and Italian army near to metiteh bila, finally they were bombed. That area was prohibited from farming activity for a long time and finally memorial built in 2013.

https://en.wikipedia.org/wiki/Sinkov%20statistic
|
Sinkov statistics, also known as log-weight statistics, is a specialized field of statistics that was developed by Abraham Sinkov, while working for the small Signal Intelligence Service organization, the primary mission of which was to compile codes and ciphers for use by the U.S. Army. The mathematics involved include modular arithmetic, a bit of number theory, some linear algebra of two dimensions with matrices, some combinatorics, and a little statistics.
Sinkov did not explain the theoretical underpinnings of his statistics, or characterized its distribution, nor did he give a decision procedure for accepting or rejecting candidate plaintexts on the basis of their S1 scores. The situation becomes more difficult when comparing strings of different lengths because Sinkov does not explain how the distribution of his statistics changes with length, especially when applied to higher-order grams. As for how to accept or reject a candidate plaintext, Sinkov simply said to try all possibilities and to pick the one with the highest S1 value. Although the procedure works for some applications, it is inadequate for applications that require on-line decisions. Furthermore, it is desirable to have a meaningful interpretation of the S1 values.

https://en.wikipedia.org/wiki/Cross-flow%20filtration
|
In chemical engineering, biochemical engineering and protein purification, crossflow filtration (also known as tangential flow filtration) is a type of filtration (a particular unit operation). Crossflow filtration is different from dead-end filtration in which the feed is passed through a membrane or bed, the solids being trapped in the filter and the filtrate being released at the other end. Cross-flow filtration gets its name because the majority of the feed flow travels tangentially across the surface of the filter, rather than into the filter. The principal advantage of this is that the filter cake (which can blind the filter) is substantially washed away during the filtration process, increasing the length of time that a filter unit can be operational. It can be a continuous process, unlike batch-wise dead-end filtration.
This type of filtration is typically selected for feeds containing a high proportion of small particle size solids (where the permeate is of most value) because solid material can quickly block (blind) the filter surface with dead-end filtration. Industrial examples of this include the extraction of soluble antibiotics from fermentation liquors.
The main driving force of cross-flow filtration process is transmembrane pressure. Transmembrane pressure is a measure of pressure difference between two sides of the membrane. During the process, the transmembrane pressure might decrease due to an increase of permeate viscosity, therefore filtration efficien

Stephen Warshall (November 15, 1935 – December 11, 2006) was an American computer scientist. During his career, Warshall carried out research and development in operating systems, compiler design, language design, and operations research. Warshall died on December 11, 2006 of cancer at his home in Gloucester, Massachusetts. He is survived by his wife, Sarah Dunlap, and two children, Andrew D. Warshall and Sophia V. Z. Warshall.
Early life
Warshall was born in New York City and went to public school in Brooklyn. He graduated from A.B. Davis High School in Mount Vernon, New York and attended Harvard University, receiving a bachelor's degree in mathematics in 1956. He never received an advanced degree since at that time no programs were available in his areas of interest. However, he took graduate courses at several different universities and contributed to the development of computer science and software engineering. In the 1971–1972 academic year, he lectured on software engineering at French universities.
Employment
After graduating from Harvard, Warshall worked at ORO (Operation Research Office), a program set up by Johns Hopkins to do research and development for the United States Army. In 1958, he left ORO to take a position at a company called Technical Operations, where he helped build a research and development laboratory for military software projects. In 1961, he left Technical Operations to found Massachusetts Computer Associates. Later, this company became part of

SOCPs can be solved by interior point methods and in general, can be solved more efficiently than semidefinite programming (SDP) problems. Some engineering applications of SOCP include filter design, antenna array weight design, truss design, and grasping force optimization in robotics. Applications in quantitative finance include portfolio optimization; some market impact constraints, because they are not linear, cannot be solved by quadratic programming but can be formulated as SOCP problems.
Second-order cone
The standard or unit second-order cone of dimension is defined as

The second-order cone is also known by quadratic cone, ice-cream cone, or Lorentz cone. The second-order cone in is .
The set of points satisfying a second-order cone constraint is the inverse image of the unit second-order cone under an affine mapping:

The second-order cone can be embedded in the cone of the positive semidefinite matrices since
